Equities take a lead role in any target-date glide path because theyâre the most reliable engine for investment growth. But even that engine could use some help in the future.
The failure to generate enough performance in the accumulation years has always shaped retirement investment decisions and will likely become an even bigger challenge in the next decade. A big reason for that is that quantitative easing by developed-market central banks has pushed down yields on both stocks and bonds toward historical lows.
All is not lost, however. We believe that combining equities with equity diversifiers may be a formula for investment growth, by helping to manage risks prudently without sacrificing returns. The role of equity diversifiers is to access other strategies that demonstrate strong growth potential but that have a more modest correlation to equity markets.
A number of good candidates exist for enhancing equities' diversification further than the traditional style (growth or value), geography and capitalization (small-, mid- and large-cap) categories.
A number of good candidates exist for enhancing equities' diversification further than the traditional style (growth or value), geography and capitalization (small-, mid- and large-cap) categories. Two appealing diversifiers to long-only equities are long/short equity and risk-parity strategies. These three categories have had essentially comparable returns over the last 25-year period, but theyâve generated their returns from different sources, and they tend to grow at different paces and at different times in an economic cycle (Display).
Long/short equity generates more than half its returns from factors outside the benchmark movements of the equity market. Whatâs important in long/short equity strategies is manager skill (think âalpha diversificationâ). That means selecting securities, exposing the strategy to different factors that offer attractive returns within the market and tactically adjusting across factors to increase returns. Those factors could be value or growth styles, quality, profitability, or momentum strategies.
Risk-parity strategies generate diversification not by selecting individual securities but by diversifying across broad asset markets (think âbeta diversificationâ). They donât rely on equity market returns alone. They their exposure across interest rates, commodities, credit and other asset classes. And they use some leverage to deliver a more consistent return pattern, structuring this part of the portfolio so that thereâs an equal risk contribution from multiple asset classes.
Thereâs a clear benefit in using both long/short equity and risk-parity strategies in glide path design. That benefit typically surfaces during sharp market plunges, such as in 2008, but itâs even more worthwhile during lengthy periods of underperformance from equities. For example, in the 10-year period from 1999 through 2008, equities delivered an average annualized return of â1.4%, while long/short equity and risk parity actually delivered stable, more consistent return patterns of 6.9% and 9.0%, respectively.
The fundamental reason for diversification holds true here: no one asset class or strategy outperforms all the time. Those divergent returns for long/short equity and risk-parity strategies wonât happen over all periods. If we diversify away from equities when theyâre the best-performing asset class, the other strategies will lag. That was the case during the bull market of the late 1990sâand that has also happened since the end of the recent financial crisis. But better diversificationâin this case, incorporating equity diversifiersâhelps create a more consistent level of growth over the long term. And we believe that adding equity diversifiers wonât sacrifice long-term portfolio growth; it will actually enhance it.

"Target date" in a fund's name refers to the approximate year when a plan participant expects to retire and begin withdrawing from his or her account. Target-date funds gradually adjust their asset allocation, lowering risk as a participant nears retirement. Investments in target-date funds are not guaranteed against loss of principal at any time, and account values can be more or less than the original amount investedâincluding at the time of the fund's target date. Also, investing in target-date funds does not guarantee sufficient income in retirement.
